Hm... bad relay?
My car has a gremlin. Surprise, surprise.
Sometimes my power wondows and sunroof work when there's no key in the ignition. I suspect they shouldn't. No other accessories do this.
Sometimes, they only work when the key is in and turned a notch or 2. I suspect this is the correct config.
So: something is intermittently allowing power to the windows and sunroof.
Relay? Ignition switch? Other?
I've pored over some diagrams, none the wiser...

From the 1985 Service Information Booklet W K D 491 721:
Power Windows
USA cars have a power window circuit which is activated via a special relay (VI - yellow print) .
Power window motors can still be operated after turning off the ignition and closing the doors .
This operation however is stopped when a door is opened . Power window motors can then be operated as required only after turning on the X contact or ignition .
In R . o. W. cars the windows can be operated with the doors open (no change in comparison to 1984 models) .
In perhaps a bit plainer English:
For USA cars after 1985, you can operate the windows and sunroof after you turn the ignition switch off - until you open a door.
For R.o.W cars, you can operate the windows even after you open a door.
If your windows will work on a USA car with a door open:
- You may have a bad door switch (the system doesn't know a door is open).
- A relay may be sticking shut (Relay X - I think)
- Someone has changed the wiring.
